To all whom it may concern:

Be it known that T, GEORGE WALLICK, a citizen of the United States, residing at Mount Vernon, in the county of Linn and State of Iowa, have invented certain new and useful Improvements in Rotatable .Fumps for Cooling Systems of Automobiles, of which the following is a specification.

My invention relates to improvements in rotary pumps, and has particular reference to such a pump designed to 'beconnected 1n the water cooling system of an internal combustion engine.

An important object of the invention is to provide .a pump of the above mentioned character, which is adapted to be rigidly and securely mounted upon the crank case of the engine, and be driven by the fan belt,

without interfering with the supporting levers of the fan, and which permits of the straight passage of the water from the radiator to the intake of the engine j acket.-

A further object of the invention is to provide a pump of the above mentioned character, having relatively few blades, equipped with flanges, extending in the plane of rotation thereof, whereby the rotor is effective in causing a free circulation of the water.

A further object of the invention is to provide a device of the above mentioned character which is self contained, extremely simple, strong and durable.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings formin a part of this specification, and in which like numerals are employed to designate like parts throughout the same.

Fig. 1 is a side elevation of the pump embodying my invention, showing the same installed upon the engine of an automobile,

Fig. 2 is a rear elevation of the pump, the same being disconnected from the engine,

Fig. 3 is a front elevation of the same,

Fig. 4 is an enlarged sectional view taken on line tl of Fig. 2,

Fig. 5 isan elevation, of the inner side of the rear casing section,

Fig. 6 is a similar view of the forward casing section,

\ 51g. 7 ma perspective view of the rotor, an a Fig. 8 is a detail horizontal on line 8-8 of Fig. 3.

In the drawings, wherein for the of illustration is shown a preferred ment of my invention, the numeral 10 designates a cy inder block of an internal coliibust1on engine, having awater jacket 11. The cylinder block is formed upon a crank case 12, having a flange 13 which is bolted to a flange 1a of the lower crank case section 15 or grease pan, Arranged in advance of the cylinder block is the radiator 16, having an outlet pipe 17 and an inlet plpe 18, which leads into the upper portion or outlet of the water jacket 11. The fan 19 is arranged between the radiator 16 and the engine 10 and is driven by a belt 20, engaging the usual pulley driven by the crank shaft of the engine.

The numeral 20 designates my 1mproved pump as a whole, arranged as shown in Fig. 1. This pump embodies a forward casing section including a flat plate 21 with a vertical depending conduitfor chamber 22 cast thereon, and extending to the center purpose embodiof the flat plate. This conduit discharges .into a central opening 23, as more clearly shown in Fig. 4. The conduit or chamber extends downwardly in the form of a depending inclined pipe or connection 24:. The chamber 22. carries a stufling box 25, rotatablyreceiving a shaft 26, and having a pulley 27 rigidly mounted thereon.

. The rear casing section embodies a chamber 28, having an internal outlet recess 29. Figs. 4 and5, arranged at a tangent. This outletrecessis formed in the face of the chamber 28 and bulges outwardly upon the same. The recess 29 leads into an outletpipe or connection 30, as shown. The rear casing section carries a standard or leg 31 formed integral therewith, and having a foot 32. The leg 31', Fig. 2, is offset laterally with respect to the casing 21, and is adapted to be bolted upon the flanges 13 and 14 of the. clamp case. By this arrangement of the leg 31, the casing 21 is suitably spaced fromthe engine. Bolts 28' connect the casing sections.

section taken The shaft 26 extends forwardl into a bearing 31, formed integral withrt e chamber 28. This bearing 31 and the stufiing box 25 are eccentric wit relation to the chamber 28, which is in the form of an involute curve, the outwardly bulging chamber being located at the outermost point of the involute curve, with an inwardly projecting flange 32, partly covering the chamber 29. The bearing 21 is adapted to receive grease and is equipped with a plug 33. The pulley 27 is engaged by the fan belt 20 and is driven thereby, as is obvious.

The numeral 34 designates a rotor as a whole, embodying a hub 35, rigidly mounted upon the shaft 26. This hub 35 carries blades 36, curved in the direction of thelr rotation. The blades 36 are provided at their rearedges with flanges 38, which operate in proximity to the face of the chamber 28.

The pipe or connection 24 is inserted into one end of a hose 39 or the like, the opposite end of which receives the pipe 17. A pipe 40 leads into the pipe or connection and also into the intake of the water jacket 11. v

The operation of the apparatus is as follows: The fan belt 20 rotates the rotor 34 in the direction of the arrow, Fig. 7, and the water is drawn into the casing '21 through the conduit 22 and through the central opening 23. The rotor then throws the water outwardly and it discharges into the pocket or recess 29'and then passes through the pipe 40 into the water jacket of the engine and then through the pipe 18 to the top of the radiator 16, as is obvious. a

It is to be understood that the form of my invention herewith shown and described, is to be taken as a preferred example of the same, and that varlous changes in the shape, size, and arrangement of parts may beresorted to without .departi-ngfrom the spirit of my invention or the scope of the subjoined claim.

Having thus described my invention, I claim: I I r A pump comprising a pump casing embodying a casing section having a chamber, said chamber being provided with an outwardly bulging pocket'within its periphery and a pipe leading into said pocket, said casing section having a leg dependingi therefrom and rigidly secured thereto and adapted to be rigidly attached to the crank case of an engine, a coacting casing section embodying a flat plate secured to the open face of the chamber and having an openin formedtherein, said plate having a radlal conduit formed thereon and leading into said opening, said conduit having an inclined pipe section connected therewith, a shaft extending through the casing section and the opening in said plate, a bearing formed upon said chamber to pivotally receive one end of the shaft, a 'bearing formed upon said conduit to pivotally receive the opposite end ofcs'aid shaft which projects forwardly beyond said bearing, the bearin carried by the conduit being arrange wholly exteriorly thereof, a pulley carried by the forward end of said shaft and driven by a belt, a rotor rigidly mounted upon the shaft, said rotor having blades which are longitudinally curved and transversely straight, said blades being provided at their edges adjacent to said pocket with flanges projecting laterally beyond the blades in their plane of rotation, a conduit connected with the pipe section of the first named casin and a second conduit connected with t e pipe of the chamber.

In testimony whereof I aflix m signature. I

GEORGE W LLICK.
